1 Product Description

ProfiHub A5 and B5 are advanced, flexibleand robust network components forPROFIBUS DP installations, which makes itpossible to implement long multi-device spurlines and backbone structures with star/treesegments.

PROFIBUS DP is a high speed communicationbus that has to comply with strict rulesconcerning spur lines, because of possiblereflections that could lead to communicationdisturbances. If spur lines or star segments arerequired, costly investments in repeaters have tobe done.

Innovative components for such applications arethe ProfiHub A5 and B5. These are perfecteconomic solutions to implement reliable spurlines in high speed DP networks. They have thefunctionality of 5 galvanic isolated transparentrepeaters . This allows network structures withextended spur lines that individually can handle amaximum of 31 devices and a length equal to themain bus. The ProfiHub A5 and B5 refresh areceived message on one Channel andtransfer it to all the other Channels (chickenfoot topology).

Because the ProfiHub A5 and B5 create isolatedsegments, the devices can now be removed andadded during operation. Also electrical busproblems and EMC disturbances in a spur do notspread to the other segments. The intelligent logicand isolation circuits of the ProfiHubs do notchange the bit width. This means the ProfiHubsdo not have limitations in serial placement. Thelogic also detects the transmission speedautomatically.

To assist the installation work, termination isintegrated and can be switched on/off. Thegrounding concept is also selectable: direct orcapacitive grounding. The ProfiHubs are powered by a 10 to 32 DC Voltage (110/230V AC versionsare also available). For troubleshooting, maintenance and commissioning the ProfiHubs are equippedwith a display on the outside, which indicate the status of each Channel (Data and Error).

1.4 Channel Structure

Every Channel is electrically isolated and is internally connected to the transparent intelligentbackbone. The termination is switchable and is being powered by the ProfiHub. The shielding of thePROFIBUS cable can be directly grounded or indirectly grounded (see the next paragraph).

1.5 Grounding System

The ProfiHubs can be grounded by 3 methods:1) Direct grounding

2) Indirect grounding (through a capacitor)3) A combination of direct and indirect.

In most cases it is recommended always to use Direct Grounding with the power supply and theshielding of the PROFIBUS cables. If you do not want to ground all or some cables to the commonground, the cable shielding should be connected to pin I. A capacitor with a parallel high valueresistor will separate the 2 potentials ( Fig. 5 ).If by accident on 1 channel the Direct Grounding is connected with the Indirect Grounding, the DirectGrounding wins.

2 Installation Instructions ProfiHub A5

2.1 Location

The ProfiHub A5 can be installed everywhere in a non-hazardous area that complies with IP 65 (DIN40 050) and the specified temperature range of -40 to +75 o Celsius.

2.2 Position

The ProfiHub A5 can be installed in every position, but it is recommended to install it with the cableglands pointing down to create a more reliable protection against moist and dust (water compartment

and glands). In this position it is also easier to read the status display.

2.3 Mounting

The ProfiHub A5 has 4 mounting holes for 4..5 mm screws ( Fig. 9 ). To reach the holes on position 1and 2, the top lid has to be removed.

1) It is recommended to mount the ProfiHub A5 with at least 4 suitable screws/bolts in position

1, 2, 3 and 4. 2) Be careful with the flat cable that connects the lid with the PCB.

2.4 Power Supply

The 4-pin screw type power connector is located on the bottom left of the PCB ( Fig. 10 ).

The power supply has to comply with the following specifications:- Voltage: 10 to 32 Vdc

- Current: Min. 130 mA- Wire diameter: < 2,5 mm 2 - Cable thickness: 5 to 10 mm

ProcedureTo connect the 24V supply to the 4-pin screw-type terminal, proceed as follows:- Strip the insulation from the cable or the conductors for the 24V power supply.- Secure the conductors in the screw-type terminal.Note: There is a grounding point that can be used.

To connect the power supply, you need a 3 mm screwdriver.

TestingIf the power is switched on it can be diagnosed by the following indicators on the PCB:- All the LEDs should be shortly blinking.- The READY LED is ON or Blinking.- The voltage LEDs are ON (5V, 3V3 and 1V8).

It is recommended to use a power supply with a ground lead (3-wire).

2.7 Termination

The termination of the Main-Channel has been set to OFF by default. If the ProfiHub is the last/firstdevice on the segment, the termination should be set to ON ( Fig. 13 ).

The termination of the Channels have been set to ON by default. Because it is assumed that the newsegment is started at the ProfiHub ( Fig. 13 ).

Dont forget to switch the termination ON at the other end of the segment and make sure it is

powered continuously.

2.8 Baudrate switch

The ProfiHub recognizes the transmission speed by default. If it is required that the ProfiHub is lockedto a certain transmission speed, switch S100 should be set to the required value ( Fig. 14 ). The switchcan be reached by removing the top lid.

To set the transmission speed, you need a 3 mm screwdriver.

DP-V0 devices (master and slaves) perform the following basic functionalities:- Cyclic exchange of I/O data between controlling and slave devices- Device, Identifier (module) and Channel related Diagnosis- Parameterization of DP-slaves- Configuration of DP-slaves

DP-V1 DP-V1 is the first stage of extension of PROFIBUS DP after DP-V0. DP-V1devices shall comply with the following features:- Device related diagnosis is replaced by status and alarms.- The first three octets of the user parameterization data are nowstandardized- Optionally these devices may support:- Acyclic communication (MS1, MS2)- If alarms are used, MS1 shall be supported

DP-V2 DP-V2 is the second stage of extension of PROFIBUS DP after DP-V1. DP-V2 devices shall comply with the following features:- Data Exchange Broadcast (DxB) for slave to slave communication(publisher/subscriber principle).- Isochronous Mode (time tick synchronized operating slaves, e.g. drives)- Up- and/or download of Load Region Data (domains)- Function Invocation- Clock Control (synchronization within slaves) and Time Stamping- Redundancy

ElectromagneticCompatibility (EMC)

The extent to which an electric or electronic device will tolerate electricalinterference from other equipment (immunity), and will interfere with otherequipment. Within the European Community as well as in other countries it isregulated by law that electric and electronic components and equipmentcomply with basic standards such as IEC 61000-6-2 or IEC 61326 or

corresponding individual product standards.

FDL Fieldbus Datalink Layer. Layer 2 of PROFIBUS.

Hub A Hub refreshes a signal and passes the information on to all nodes whichare connected to the Hub. Data frames which were received on one port aretransferred to all the other ports (chicken foot topology).

MPI Multiple Protocol Interface. A by Siemens defined protocol which uses thelayer 1 and 2 of PROFIBUS (FDL).

PCB Printed Circuit Board.

PROFIBUS DP Acronym for "PROFIBUS for Decentralized Peripherals". Specification of anopen fieldbus system with the following characteristics:- Polling master-slave-system (cyclic communications, MS0)- Flying masters with robin round token passing coordination (MM)- Connection based (MS1) and connectionless (MS2, MS3) acycliccommunication between masters and slavesOptions (e.g.):- Data exchange broadcast (DXB), i.e. slave to slaves communication- Isochronous mode of slaves- Clock synchronization

- RedundancyPROFIBUS DP is standardized within IEC 61158 and IEC 61784,communication profile families 3/1 and 3/2The term "PROFIBUS DP" also is a synonym for the RS485 baseddeployments within factory automation.

Repeater Active physical layer device that receives and retransmits all signals over adifferent port to increase the distance and number of devices for whichsignals can be correctly transferred for a given medium.

Spur A cable connecting a node to a bus segment. Spurs are not recommended inPROFIBUS DP and prohibited with 12 Mbps and PROFIsafe operations.

German term is "Stichleitung".

Termination A powered resistor network at both ends of a segment to prevent reflections(for PROFIBUS DP).

Topology In a communications network, the pattern of interconnection betweennetwork nodes; e.g. bus, ring, star configuration.
